How the 7313-BEP model number is decoded

7313 BEP is SKF's 65 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 65×140×33 mm to the ISO dimension plan. 40° contact angle (suffix B): the steep standard single-row angle, giving the highest axial capacity at the cost of speed, with a recommended load ratio Fa/Fr ≥ 1. E marks the optimized internal design with an enhanced ball complement and race geometry. glass-fibre reinforced PA66 cage, ball-centred (suffix P), with a 120 °C continuous-temperature ceiling. The plain BEP is a basic single bearing: its faces are not ground for universal matching, so defined pairs require the BECBP execution rather than two arbitrary BEP units.. Envelope 65×140×33 mm (2.559×5.512×1.299 in), 37.5 mm radial section height, C 108 kN, C0 80 kN, Pu 3.35 kN.reference speed 6,000 r/min (thermal) and limiting speed 5,600 r/min (mechanical), catalogue mass 2150 g. Speed planning distinguishes the two published ceilings mechanically: the cage and balls tolerate 5,600 r/min while thermal balance under catalogue load sets the 6,000 r/min reference; at dm ≈ 102.5 mm the corresponding dn is approximately 574k mm·r/min. Sizing arithmetic on the 65 mm bore: 108 kN C divided by the 37.5 mm radial section height gives 2.9 kN per section millimetre; the 2150 g mass and 3 % Pu/C share frame the light-load floor for the adjusted-life check. Speed-ratio note for this exact unit: the reference speed is 6,000 r/min against a 5,600 r/min limiting speed, i.e. a reference-to-limit ratio of 1.07. Basic polymer-cage execution: BEP is delivered as an individual open bearing with the 40-degree optimized internals and a glass-fibre PA66 ball-centred cage; it is not ground on the side faces for arbitrary pairing, so a reversing-thrust position should order BECBP for a set rather than mounting two unmatched BEP units.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• One 7313-BEP locates the shaft in one axial direction only; reversing-thrust positions need a DB or DF pair — or a double-row bearing — with preload set from the load diagram, never from assembly feel.
• At 65 mm bore the k5 seat assumes a steel shaft and housing; aluminium housings grow faster with temperature, so re-check the outer-ring setting when the case is non-ferrous.
• Mount by induction-heating the inner ring to max 120 °C — the PA66 cage sets the ceiling, not the steel; driving the bearing home through the outer ring or balls brinells the asymmetric raceway.
• Preload the set against a calculated stand-off dimension — the ground faces of BEP establish it, but locknut torque, sleeve crush and housing-face squareness each consume part of the allowance.
• The steep 40° angle of 7313-BEP favours thrust-heavy combined loads; for a predominantly radial high-speed position the 25° ACCBM execution of the same size is the alternative order number.
• Catalogue ratings are SKF PUB BU/P1 17000 figures for 7313 BEP as the single basic pa66 execution; the other order numbers of the 7313 size are different products and may carry different ratings — always quote the full designation when purchasing.
